The TridentII is a 13.41m-long missile with a diameter of 2.11m. Weighing approximately 130,000lbs (58,500kg), the missile has a considerably larger payload capability than the Trident I (C4). All three stages of the Trident II have lighter, stronger and stiffer graphite epoxy structures, resulting in major weight saving. The missile features an ae...
The navigation subsystem of the Trident II D5 has been redesigned to achieve accuracy and maintain an extended fix interval. An electrostatically supported gyro navigator (ESGN) was adopted as the inertial navigator, while a navigation sonar system (NSS) with high capacity was added to measure velocity. The global positioning system (GPS) replaced ...
The Trident II D5 missile is launched from a submarine. It was deployed for the first time in 1990 and is currently carried by the US Navy’s Ohio-class and the UK Royal Navy’s Vanguard-class submarines. Each Vanguard-class submarine has 16 missile tubes and ejects missiles by using high-pressure gas. The Ohio-class submarines can carry up to 24 sub...
Trident II missiles are capable of carrying W76 or W88 multiple independently targeted re-entry vehicles (MIRVs). The MIRV is composed of an arming, fusing and firing (AF&F) assembly, a nuclear assembly, and electronics. The AF&F assembly protects the warhead from detonating during storage and restrains re-entry vehicle detonation until all qualify...
The Trident II D5 missile is powered by a three-stage solid-propellant rocket. The boost motor systems for all the stages are supplied by Alliant Techsystems (ATK), a subsidiary of Northrop Grumman. The third stage motor of the missile incorporates a low-cost high-performance propellant, a low-erosion ceramic rocket nozzle throat, and a lightweight...
